What is the first medication to give to a patient with an allergic reaction causing wheezing?

Correct Answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is a fast-acting bronchodilator that helps relieve wheezing by relaxing the muscles in the airways, making it the first-line treatment for wheezing caused by bronchospasms in allergic reactions. Methylprednisolone (Choice B) is a corticosteroid used for its anti-inflammatory properties and is typically given after bronchodilators. Cromolyn (Choice C) is a mast cell stabilizer that is used for the prevention of asthma symptoms, not for immediate relief. Aminophylline (Choice D) is a bronchodilator that is less commonly used nowadays due to its narrow therapeutic window and potential for toxicity.

Correct Answer: A

Rationale: A CD4 T-cell count below 180 cells/mm3 should be prioritized for a patient with HIV. This value is crucial as it indicates severe immunocompromise in HIV-infected individuals. Monitoring CD4 T-cell count helps assess the status of the immune system and guides treatment decisions. Serum albumin levels (choice B) may reflect the patient's nutritional status and overall health but are not as specific to HIV disease progression. White blood cell count (choice C) and hemoglobin levels (choice D) can be affected by various factors and are not as directly linked to HIV management as the CD4 T-cell count in this context.

Correct Answer: A

Rationale: Administering sublingual nitroglycerin is the priority initial action for a patient with chest pain and acute coronary syndrome. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart muscle and reducing chest pain. Checking the patient's urine output (choice B) and cardiac enzymes (choice C) are important assessments but are not the first priority when managing acute chest pain. Obtaining IV access (choice D) is essential for administering medications and fluids, but administering sublingual nitroglycerin takes precedence in the initial management of chest pain in acute coronary syndrome.

Correct Answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the nurse should tighten the connections of the chest tube system. This action can often resolve an air leak causing the continuous bubbling. Clamping the chest tube or replacing it would not address the underlying issue of an air leak and may lead to complications. Continuing to monitor the chest tube without taking corrective action may result in the deterioration of the patient's condition.

Correct Answer: A

Rationale: The correct answer is A: Irritability, confusion, restlessness. These are common signs of Increased Intracranial Pressure (IICP) as they result from the increased pressure on brain tissue. Choices B, C, and D are incorrect. Fatigue and shortness of breath (SOB) are not typical symptoms of IICP. Changes in pupillary response can be seen in other conditions but are not specific to IICP. Elevated blood pressure is not a common sign of IICP.

Correct Answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart, relieving chest pain, and preventing cardiac tissue damage. Establishing IV access (choice B) is important but not the preferred initial treatment for unstable angina with chest pain. Auscultating heart sounds (choice C) and obtaining cardiac enzymes (choice D) are relevant assessments but do not address the immediate symptomatic relief needed for a patient with unstable angina and chest pain.

Correct Answer: A

Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.

Correct Answer: A

Rationale: Patients diagnosed with hypokalemia are at risk for cardiac dysrhythmias due to low potassium levels. Hypokalemia can lead to abnormalities in the electrical conduction system of the heart, potentially causing irregular heart rhythms. Muscle weakness (Choice B) is a symptom commonly associated with hypokalemia, but the question asks about conditions the patient is at risk for, not specific symptoms. Seizures (Choice C) are not typically associated with hypokalemia; they are more commonly linked with conditions such as epilepsy. Bradycardia (Choice D) refers to a slow heart rate, which is not a typical risk associated with hypokalemia; instead, tachycardia (fast heart rate) is more commonly observed in patients with low potassium levels.

Correct Answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This intervention is a priority for a patient with possible acute coronary syndrome because nitroglycerin helps vasodilate coronary arteries, increase blood flow to the heart muscle, relieve chest pain, and reduce cardiac workload. Obtaining cardiac enzymes (choice B) is important for diagnosing myocardial infarction but is not the initial priority. Getting IV access (choice C) is essential for medication administration and fluid resuscitation but is not the priority over administering nitroglycerin. Auscultating heart sounds (choice D) is a routine assessment but does not address the immediate need to relieve chest pain and improve blood flow to the heart in acute coronary syndrome.
